iio: ak8975: fix maybe-uninitialized warning
If i2c_device_id *id is NULL and acpi_match_device returns NULL too, then chipset may be unitialized when accessing &ak_def_array[chipset] in ak8975_probe. Therefore initialize chipset to AK_MAX_TYPE, which will return an error when not changed. This patch fixes the following maybe-uninitialized warning: drivers/iio/magnetometer/ak8975.c: In function ‘ak8975_probe’: drivers/iio/magnetometer/ak8975.c:788:14: warning: ‘chipset’ may be used uninitialized in this function [-Wmaybe-uninitialized] data->def = &ak_def_array[chipset]; Signed-off-by: Richard Leitner <dev@g0hl1n.net> Cc: <Stable@vger.kernel.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
